+= Orphaned hyphae
+Page [[/orphans]] lists **orphaned hyphae**, or orphans for short. An orphan is a hypha with no backlinks, i/e not linked anywhere. Being part of a [[/help/en/category | category]] does not de-orphan the hypha.
+
+This page can be used in some workflows. For example, you may create several hyphae, and get back to linking them later. Locating them in this list might help you.
